In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is two or more.

[0026] The present utility model provides a tool changing device for a double turret machining center as shown in Figures 1 - 3 Figure 1, which includes a machining center main body 1, a driving mechanism 2, a first tool head 3, a control mechanism 4, a machining base 5, a first main shaft 6 and a second tool head 7. A driving mechanism 2 is arranged on the machining center main body 1, the first tool head 3 is connected to the driving mechanism 2, a control mechanism 4 is arranged on the machining center main body 1, a machining base 5 is arranged at the inner bottom of the machining center main body 1, a first main shaft 6 and a second main shaft 8 are respectively arranged on both sides of the machining base 5, and the second tool head 7 is detachably connected to the first main shaft 6 through a coupling 603. The driving mechanism 2 and the control mechanism 4 in this embodiment are conventional existing technologies and will not be elaborated here.

[0027] In this embodiment, a cover plate 601 is installed on the side of the first main shaft 6. A motor 602 is arranged inside the first main shaft 6. A coupling 603 is installed on the output shaft of the motor 602.
